1386624 – SELinux prevents dhclient from name_bind on ephemeral port

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Stef Walter 2016-10-19 10:15:47 UTC

Description of problem:

During the Cockpit integration tests we see this SELinux issue during the tests. It does not seem to affect the test behavior:

Error: type=1400 audit(1476871118.797:4): avc:  denied  { name_bind } for  pid=1454 comm="dhclient" src=61000 scontext=system_u:system_r:dhcpc_t:s0 tcontext=system_u:object_r:ephemeral_port_t:s0 tclass=udp_socket

Version-Release number of selected component (if applicable):

[root@localhost ~]# rpm -q dhclient
dhclient-4.2.5-47.el7.x86_64
[root@localhost ~]# rpm -q selinux-policy-targeted
selinux-policy-targeted-3.13.1-93.el7.noarch
[root@localhost ~]# rpm -q NetworkManager
NetworkManager-1.4.0-0.5.beta1.el7.x86_64

How reproducible:

Rarely.

Comment 4 Miroslav Grepl 2016-10-20 08:48:59 UTC

Pavel,
is it expected that it binds ephemeral ports? Or is it a fallback?

I don't think we should need to use them.

Comment 7 Stef Walter 2016-12-19 10:25:38 UTC

This happens rarely, but weekly in the Cockpit integration runs. Maybe once every few thousand runs. Here is such a case:

Comment 10 Peter 2018-01-02 14:54:24 UTC

The related bug is https://bugzilla.redhat.com/show_bug.cgi?id=1299562 that is fixed. So I think this one should be as well.

Comment 11 Pavel Zhukov 2018-04-13 13:19:13 UTC

Fixed in dhcp-4.2.5-60.el7
